SOURCE: Delonghi dcm 485 power on but will not brew

THANKS "Guest" - you just saved me $100 !
I had already bought a new coffee maker (Krups) when I came across your post.  The thermal fuses (there are two of them) are indeed hidden - they are right underneath the metal braces/clamps that push them against the heating element that they are meant to monitor.  If you take off these clamps and pull back the white insulation you can easily replace the fuse(s).  What you need is:
- volt meter
- needle-nose pliers
- Radio Shack thermal fuse 228C (catalog #270-1321) - these are rated at the same temperature and look fairly identical.  They cost $1.69 at your local Radio Shack
You do NOT need a soldering iron.  So: - take off the bottom of the coffee maker - take off the clamp(s) and pull back insulation. - put your volt meter on either side of the fuse and check for continuity.  In my case, one had no resistance (good) and the other had no connection (bad). - take your needle nose and pry open the clips on the end of the wires that connect to the bad fuse ... put in the new fuse (make sure the polarity matches ... just in case) and scrunch the clips together again - replace everything
In order to make this easy to do, I disconnected the water intake/outtake and also removed the two screws holding the whole heating assembly.  Made it a lot easier

SOURCE: Delonghi Magnifica Makes creaking noise when preparing brew unit

These machines do need to be lubricated every so often. First, buy some food safe lubricant, e.g. here. Then, turn the machine off, open the front door, and remove the infuser. There is a holder connected to the machine by two hex screws. You may remove this (or even just leave it on). Now attach a long tube to the lubricant (should come with the can) and spray lubricant on both sides of the vertical screw that moves the infuser up and down. Give it a few good sprays on both sides of the screw, up and down, and that should solve your problem.

SOURCE: wont heat or brew!!

Make sure the coffee maker is unplugged there's 120 lethal volts inside when plugged in!

This unit has a replacable thermal fuse. It's a "Microtemp" Thermal Cutoff Fuse G4A00. You can buy five on eBay for $2.70. There are two on this unit and they are in the base concealed inside a 3" white mesh that runs alongside the heater. You will need a security fladebladed screwdriver that you can make by filing a notch in the center of a regular screwdriver.

Gaggia accademia grinds too much


Make sure that your brew unit is clean and lubricated. The CPU on the machine uses the brew unit to calculate the amount of coffee it grinds. If the brew unit is dirty and hard to turn strange things will happen.

Leak whenever I make a cup of coffee


Hi,

Please consider the following:

1. Descaling (Machine should be descaled every after 3 months, every 500 brews, every time the machine prompts you to do so..(whichever comes first)..)

2. Lubricate the brew unit / Clean the brew unit with running water

3. Run hot water through the nozzle / Run how water only through the spout (to check clogs)

~ if above mentioned are no good, contact the customer service for the nearest ASC

the saeco brew unit is the same as a Miele brew unit from a cva 615. check to see if there are any Miele service centers near you. The brew unit needs to be lubricated with food grade silicone grease every 30 days. if you dont do that, the plastic gears in the gearbox can and will strip. Try to find another brew unit and see if it works with a different one. If not, you may need to send it in to a repair center.

Brew unit warning light keeps flashing even when brew unit is properly engaged


Hi
Try pushing on the upper left side of the brew unit when its installed. If you hear a click, it should have cleared the light. If so you need to lubricate the outlet pipe on the brew unit. It is dragging on the brew unit when you are trying to install it. This will allow it to seat correctly. Use a food grade lube like what came with your Saeco.

Magic deluxe does not have enough power


Hi
There are a couple of things you can check. Make sure that the dosing lever is not all the way to full charge. 1 click back from full is the best for strong drinks. Make sure that the grind is not too coarse as this takes up more space and is hard to compress. Check the brew units guides inside the sides of the brew unit. They can be clogged with coffee especially at the top by the brew head. Use a Q tip and clean the guides, they don't need to be lubed. And last the brew unit needs to be lubricated where the O-rings and seals are but only there. The big O-ring on the brew head. Inside the receiver tube on the back side of the brew unit (lube inside the piece top to bottom. And finally turn the brew unit upside down.
There is a rd with a wishbone looking thing in the end of the rod. Lube the rod towards the center of the brew unit. This will lube the seal in the brew chamber. Try these suggestions and see if they don't help?

How do I disassemble and clean the brew unit motor on my Jura Capresso E8? The machine will brew coffee but it goes through about three cycles to get the grounds to eject and be ready to brew again. I have...


I have some good instructions I downloaded from www.kaffeestudio.com . They are in German, but with many pics. If you are technically adept, then it is really no prblem. You should put in new o'rings and lubricate with the food grade silicon grease before reassembly, otherwise it won't be long before you are doing it again. Give yourself about 3 hours to perform this task the first time. One thing to remember. The cleaning tablets tend to strip the lubrication from the brew units, subsequently binding up the brew unit, sometimes tearing the o'rings and giving the malfunction 8. Plan on this being an ongoing maintenance exercise. Plan on at least once every year or two to have to do this.

My F9 displays Malfunction 8


Malfunction 8 is related to the brew unit typically. It is usually an indication of the brew unit motor having to work too hard to move the brew unit up and down. This is usually cured by disassembling, cleaning, replacing any o'rings that may be bad, and lubricating the unit, then reassembly.
I have had to do this twice on an an E75 and an E8. I finally broke down and bought seal kits and food grade lubricant for doing this. (I have only been able to buy parts from Europe online) One could by a new brew unit off of e-bay and change out the whole thing. But a simple cleaning or rebuild will typically suffice. One note. The cleaning tablets tend to strip the lubricant from the inside of the brew unit over time. Ocassionaly the seals in the brew unit will fall apart and bind up the unit. Either of these is usually accompanied by a sound of the brew unit motor straining to cycle the machine. If you are not savy in repairing it you may want to send it in. I suspect they will tell you it needs a new brew unit aand quote about $300 USD for the repair. About two hours, much patience, and about $10 in parts is most likely all it may need.

No coffee, water going to the drip tray


OK, so this is a problem with your brew unit. The unit is not cycling correctly to tell the water to come through.

We had another problem like this just this week.

The wat we fixed it was 1) Give the Brew Unit a really good clean. 2)Make sure the Brew Unit can complete a cycle - manually rotate the brew unit components through a cycle 3) Lubricate the Brew Units moving parts if necessary using some Saeco or Other Food Grade Lubricant

Then try watch a complete coffee cycle by leaving the side door of your machine open, and tricking the micro switches into thinking the door is closed by engaging them with some card or something similar.

Let us know if this does not resolve your issue.
